END PLATE FOR SPRINGS.

srncrrrcnrrolv forming part of Letters Patent rte-775,554, dated November 22, 1904. Application filed November 24, 1902; Serial No. 182,560. (No model.)

To all whom it may concern:

Be it known that 1, JOHN CARROLL, a citizen of the United States, and a resident of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in End Plates for Springs, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of semielliptic or analogous springs used on trucks of locomotives and cars.

The object of the invention is to provide said springs with end bearings which shall be simple and inexpensive in construction and shall permit said bearings to be readily and conveniently applied to the ends of the spring and afford greater and stronger holds to their connection; and to that end the invention consists in the improved construction and combination of parts hereinafter described, and illustrated in the annexed drawings, in Which Figure 1 is a side elevation of a spring equipped with my improved end bearings. Fig. 2 is a top plan View of the same, and Fig.

3 is an enlarged isometric View of the bear-. ing-plate and adjacent end portion of the spring separated from each other.

Similar letters of reference indicate correcontact With the aforesaid keys, and thus relieve the spring from wear and abrasion incident to such contact.

My improved construction of the bearingplate 6 and its connection with the spring is as follows: I maintain the bottom leaf or main leaf a to its full width throughout its length and depress the end of said leaf transversely and form said depressed portion with a horizontal tongue f, which extends across the entire width of the leaf, as shown in Fig. 3 of the drawings. The bearing-plate c I form with two parallel planes h it, constituting two bearings, each of which extends uniformly across the entire width of the plate. In the offset d between the two planes is an under- 'to form an entrance 9 for the tongue f into the groove Z through the side of the plate, and

'thus couple the plate a to the spring by sliding one of said parts laterally upon the other. The object of extending the interlocking portions of the spring and its bearing-plate completely across said parts is to facilitate the manufacture thereof.

The hanger c, passing through the slots Z) in the spring and through the slot n in the plate 6, serves to prevent lateral displacement of said plate on the spring.

.It will be observed that my invention obviates the necessity of tilting either the spring or the bearing-plate endwise to effect the coupling of said parts, and the interlocking tongue and groove of said couplingare extended across, the entire width of the spring and bearing-plate and are thus of maximum length and of correspondingly increased strength. In addition to this my invention possesses great simplicity of construction and reduces the cost of its manufacture accordingly.

What I claim as my invention is- 1. In a semi-elliptic oranalogous spring, the combination of the main leaf having its end formed with a tongue extending across the leaf and in a different plane, the adjacent leaf having its end portion extending over said tongue, and a plate formed With two bearings in different planes, each of which receives the end portion of one of said leaves as set forth.

2. In a semi-elliptic or analogous spring, the l extending through the sides of the plate and main leaf formed with a depressed end, terreceiving the aforesaid tongue through the IQ minating in a tongue extending across the end of the groove as set forth. entire width of the leaf, in combination with a bearing-plate formed with two parallel JOHN (JARROLL' planes each extending uniformly across the Witnesses: entire width of the plate and an undercut JOSEPH MORAN,

groove in the offset between the two planes CHAS. CARROLL.
